The main purpose of this monograph is to give
an elementary and self-contained account of the existence of
asymptotically hyperbolic Einstein metrics with prescribed conformal
infinities sufficiently close to that of a given asymptotically
hyperbolic Einstein metric with nonpositive curvature. The proof is
based on an elementary derivation of sharp Fredholm theorems for
self-adjoint geometric linear elliptic operators on asymptotically
hyperbolic manifolds.
